SPECIFICATION forming part 0f Letters Patent NO. 784,341, dated March 7, 1905.

Application filed July 16,1904. Serial No. 216,768.

To n.17/ whom, it may concern,.-

Be it known that 1, LLOYD S. Monnow, a citizen of the United States of America, residing' at Monessen, in the county of festmoreland and State ot' Pennsylvania, have invented certain new and uset'ul Improvements in Switches, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to switch-throwing devices, and more particularly to that class which are employed upon electric railways; and the object oi'this invention is to provide a device of this character which may be operated by the motorman of a car without the motorman leaving said car.

Another object of my invention is to construct a switch-throwing device which will bc extremely simple in construction, strong and durable, and highly eiicient in operation, the

construction of the switch will be servicable,

and it will be impossible for the same to be affected by the conditions which may surround the same.

1t is a well-known fact that the switchthrowing devices which are now commonly employed upon electric railways are many of them operated by electrically-actuated appliances and are often rendered useless by water and the electrical c'ircuitswhich surround the same, and in providing my improved switchthrowing device I have endeavored to overcome the many disadvantages of such devices heretofore used and construct a device which will be manually operated.

Brieiiy described, my improved switchthrowing device consists of locating a casing in the road-bed of the railway adjacent to the switch tongue, and I have provided novel mechanism within the casing which when operated will throw the switch-tongue in any desired direction, and upon the car l construct a device which the motorman can operate to throw the switch-tongue without leaving the car. ln the casing is provided a plurality of levers which are so connected to the switchtongue as to throw the same in one or the other direction, these levers being operated by a rod which is adapted to be depressed by the motorman to engage the mechanism carried within the casing to throw the switchtongue.

All ot' the above construction will be hercinafter described in detail.

Referring' to the drawings accompanying' this application, Figure 1 is a top plan view of the casing containing my novel mechanism, showing the same located in the road-bed of a railway adjacent to the switch-tongue. Fig. Q is a similar view with the lid ot' the casing removed. Fig. 3 is a longitudinal sectional view ot' the casing. the casing, showing the relative position ot' a car over the same, said car carrying' the operating' mechanism; and Fig. is a side elevation of a portion of the casing, showing a car about to pass over the same.

Throughout the several views oi' the drawings like numerals ot' reference indicate like parts.

The reference-numerals 1 and 2 indicate the main rails of a track and 3 and f1 the rails of a siding' which enters the main track, and thc reference-muneral 5 indicates a switch-tongue which controls the movement of the car over the main track and the siding, and to operate this switch-tongue I employ a casing 6, which is mounted within the road-bed between the tracks 1 and 2- and adjacent to the switchtongue. The casing is preferably oblong in shape and is provided with a lid 7, which may bei secured' upon the same by any desired means. The one side ot' said casing is provided with an opening 8, through which a rod 9 protrndes and is connected to the switchtongue 5. The'bottom 10 of the casing is out away at its one end to vform a recess 11 horizontally within the casing, and formed in the bottom of the casing are the longitudinal recesses 12 and 14.

The re't'erencc-numerals 15 and 16 indicate two 'bell-cranks, which are pivotally mounted, as indicated at 17 17, upon the bottom ot' the casing, the one end ot' cach bell-crank being connected, as indicated at 1S 1S, to the rod 9, whilc to the other end of the bell-cranks are pivotally connected, as. indicated at 19, rods 2.0 21, these rods being mounted within the longitudinal recesses 12 and Hand having their outer ends pivotally connected, as indi- Fig. 4 is an end View ot' TOO cated by the reference-numeral 22, to -upwardly-extending levers 23 .24, these levers being mounted upon a pin 25, journaled in the bearings 26 26 26, mounted upon each side of the recesses 12 and 14;. The upper ends of these levers are beveled, as indicated at 27, and they protrude through slots 28 29, formed in the lid 7 of the casing.

The reference-numeral 30 indicates guardblocks, which are mounted upon the lid at each side of the slots.

The operating mechanism of the construction just described consists of rods 31 32, which are mounted vertically within a yoke 33, this yoke being secured under the platform 34 of a car, and the rods 31 32 pass through openings 35, formed in the platform, and have secured on their upper ends treadblocks 36 36, and interposed between the vtread-block and the yoke are spiral springs 37v 37, which surround the rod 31 and normally hold the tread-block in its raised posij tion:

tread-block 36, which would force the rod 31 downwardly, and upon the car passing over the forward end of the casing 6 the lower end of the rod 31 would strike the beveled end 27 o f the lever 23 and move the same sufliciently to throw the rod 21 forward and throw the lever 9 through the medium of the bell-crank 16, whereby the switch-tongue would be moved away from the main rail to permit the passage of the car. Should it be desired to pass onto the siding when the switch-tongue is in an open position, the motorman depresses the other tread-block, which forces down the'rod 32, and it will strike the lever 24 and through the-medium of the rod 2O and bell-crank 15 the lever 9 will be operated to close the switchtongue. It will be observed from the connections of the levers that when the lever 23 is operated the lever 24, rod 20, and bell-crank 15 will befm/oved to the reverse position to what it assumed before the lever 23 was engaged by the rod 31, this movement being true of the lever 21 and bell-crank 16 when the rod 32 strikes the lever 24.

By the novel form of construction shown and described it will be seen that it will be impossible for electric circuits or water to afect the general operation of the device, and while I have herein shown a preferred form of arranging the levers and operating the mechanism within the casing l do not care to limit myself to this special construction, but may vary the same, as will be permissible by the appended claims.

VVhatI claim is- 1. The combination .with a switch-tongue and a casing located adjacent to said tongue, the bottom ofsaid casing being formed with a transverse recess and longitudinal recesses communicating with said transverse recess, of a rod located in said transverse recess, said rod projecting through the side of the casing and being connected to the switch-tongue, two bell-crank levers pivoted in said transverse recess and pivoted to said rod, the opposite ends of the bell-crank levers extending inwardly toward one another, rods connected to the inwardly-extending ends of the. bellcrank levers and extending through the longitudinal recesses, pivoted levers connected to said rods and extending through the top of the casing, spring-retracted tread-blocks carried by a car and rods carried by said treadblocks and adapted to contact with said pivoted levers.

2. The combination with a switch-tongue of a casing located adjacent thereto, a horizontall y-movable rod projecting through the side of the casing, and connected to the switchtongue, bell-crank levers arranged within the casing, said bell-crank levers having each one end attached to said` rod and the other ends of said levers projecting' in opposite directions one to the other, rods connected to the oppositely-projecting ends of the bell-crank levers, vertically-disposed levers pivoted in the casing and attached to said rods and projecting through the top of the casing, and vertically-movable rods mounted on a car and adapted each to contact with one of said levers to move the switch-tongue in one or the other direction.

In testimony whereof I aiiix my signature in the presence of two witnesses.

LLOYD S. MORROW.
